Here's a breakdown:
* Ore: A naturally occurring solid material from which a valuable mineral can be extracted profitably.
* Rock: A naturally occurring solid aggregate of minerals.
* Ore Rock: A specific type of rock containing a valuable mineral or minerals.
For example, consider iron ore:
* Iron ore: The source of iron metal.
* Rock: Iron ore can be found in various types of rocks, like hematite, magnetite, and goethite.
* Ore Rock: The specific rock containing hematite, magnetite, or goethite that is considered economically viable to mine for iron.
Essentially, ore rock is a rock containing a mineral of economic interest. The rock itself isn't the valuable material; it's the concentrated mineral within the rock that makes it worthwhile to mine.
